无法更新Android中SQLite数据库的数据

Question

I try to update my data in the SQLite database but when I do db.update the ide through an error and convince me to create a local var for it

public void updateEmployee(int sno, String name, double increment){
        SQLiteDatabase db = this.getWritableDatabase();
        ContentValues v= new ContentValues();

        v.put("mytag sno", sno);
        v.put("mytag name", name);
        v.put("mytag increment", increment);

        db.update("myemployee","sno=?", new String[]{String.valueOf("sno"),new String[]{});
        db.close();

    }

Answer 1

Try using

db.update("myemployee",v, "sno=?",new String[]{String.valueOf("sno"));

As update statement works like this

database.update("Table name","Contentvalues",where clause, value of where clause);
